3S Challenge

3S Challenge

The Baer Brakes 3S Challenge will be part of LS Fest West once again! 3S Challenge stands for Speed, Stop & Steering and combines elements of autocross and speed-stop into a single event that will test the ultimate limits of car and driver. Car balance, power, suspension set-up, brakes, along with driver skill and focus will be the keys to fast times. The 3S Challenge will be fun for both participants and spectators alike. The 3S Challenge is part of the Grand Champion competition and will be held in place of the autocross on Sunday. It will be open to all participants signed up for autocross.


2023 LS Fest West 3S Challenge Rules:

Since 2021, the Kumho V720 ACR tire has been excluded for use in competition. It will no longer be allowed in future Holley events. Any vehicles participating at the event with these tires installed will be automatically transitioned to an exhibition class and the times will not count towards points in Autocross or Grand Champion. 

The 3S Challenge is a competition featuring speed, stop and steering (3S).  The format will be a side-by-side low speed down and back course layout that will feature a 180-degree turnaround, slalom, and a stop box.  Course layout will be dependent on the available space.  Each “run” will be a total of left side course time added to right side course time.  In order to earn a timed run, each segment of the run must be clean.

**See tire and helmet description in rules.
